AT27C400 Datasheet 4-megabit 256k X 16 Or 512k X 8 Otp Eprom

Manufacturer: Atmel (now Microchip Technology)

Overview: AT27C400.

General Description

The AT27C400 is a low-power, high-performance 4,194,304-bit one-time programmable read only memory (OTP EPROM) organized as either 256K by 16 or 512K by 8 bits.

It requires a single 5V power supply in normal read mode operation.

Any word can be accessed in less than 70 ns, eliminating the need for speed-reducing WAIT states.

Key Features
